sidered as undulatory and vibratory; although in some in- 

 stances direct perpendicular shocks were certainly felt. The 

 second class was remarked to be attended by a noise like that 

 of a flight of birds and gusts of wind, and in some cases similar 

 noises to those already mentioned followed or preceded the 

 third class. Noises were frequently heard as if proceeding 

 from the earth, and the expectation which they occasioned of 

 the usual shock was never disappointed. 



The direction in which the motion travelled was, as almost 

 every other part of this phenomenon, disputed ; many (of 

 which I was at first one) believed that the direction was nearly 

 from N.E. to S.W. The most general opinion, and which 

 appears since to be corroborated by circumstances, was, that 

 it was from S.W. to N.E. 



The severe effects of the shock of the 16th were principally 

 confined to the province of Cutch, the damage done to other 

 countries even bordering on it being comparatively trifling ; 

 and it is remarkable that the shock appears to have been more 

 severely felt in many distant countries than it was in those in- 

 termediate, and even in some closely bordering on Cutch. 

 The great shock was felt at Calcutta about twenty minutes 

 past eight o'clock ; which, when corrected to the longitude 

 of Bhooj, will give six minutes past seven o'clock P.M., or 

 eighteen minutes later than the shock was felt in Cutch. 



At Chunar the severe shock was felt at seven minutes past 

 eight o'clock P.M. on the 16th, equal to 7 h 15 m 16 s Cutch 

 time. 



At Pondicherry it was experienced at eight P.M., equal to 

 twenty minutes past seven o'clock Bhooj time. 



At Ahmedabad the shock occurred about seven o'clock; 

 but at Broach, which is little more than 3° E. of Bhooj, it 

 occurred at nineteen minutes past seven o'clock, corrected by 

 observation *. This extraordinary variation in the moment 

 of the occurrence of the great shock can hardly be accounted 

 for by neglect or error in fixing the moment, or from errors 

 in the watches.
